trail() [2/2]

void MayaFlux::Kakshya::FrameSeekProcessor::trail	(	double	write_head,
		Kinesis::TimeMap	lag
	)

Trail a stream that is being written, by a lag that can change.

Sets a time map that follows write_head at this processor's frame rate minus the lag, so the rate is the one frames are appended at. The clock restarts at zero, so pass the write head as it is now.

Parameters

write_head	Index of the next frame to be written.
lag	Distance behind the head in frames, per second since the restart.
